I have computed lip sync from scene audio and trancript with the proper format and files, and visemes are produced, but no physcial mouth shapes appear at all. I am on version 23.6 Mac OS.
I have tried with stock puppets and it works well. When I am using an imported puppet, the visemes are computed, but for the playback there are no mouth movements or shapes. The lip sync is armed. I have troubleshooted by disarming everything except lip sync, this still has not worked. I have re imported the puppet, and this still does not fix the problem. Computing 3 takes from scene audio works, but the results are very poor for the lip sync.
Any advice would be greatly appreciated for troubleshooting. I am happy to send the file over for someone to help me take a look at.
